ABSTRACT:
A bearing liner between inner and outer bearing rings, one stationary and the other rotatable, is fixed to the stationary bearing ring. A pair of electrical conductors, coiled in at least one loop encircling the inner bearing ring, is embedded within the bearing liner. The electrical conductors are electrically isolated and located such that wear of the bearing liner causes the rotatable bearing ring to contact and electrically connect the electrical conductors. An electrical circuit detects the electrical connection to indicate wear of the bearing liner.
